Sunlite 03610 LU70/MED High Pressure Sodium Lamp
The Sunlite 03610 LU70/MED is a 70-watt high pressure sodium bulb designed for outdoor street and parking lot fixtures. It uses a standard ED17/MED form factor and E26 medium base, enabling compatibility with many HID fixtures. With a brightness of about 6000 lumens and a warm 2100K color temperature, it delivers strong, steady illumination for perimeter lighting and industrial outdoor areas. The clear glass design helps maximize light output and efficiency, while the robust life expectancy supports reduced maintenance over time.
Rossesay LU150/MOG 150W Street Bulb
The Rossesay LU150/MOG is a 150-watt HPS bulb with an E39 mogul base (MOG) and ANSI code S55. It outputs a bright, expansive field of light suitable for larger outdoor spaces. At 2100K, the warm color can enhance nighttime ambiance while maintaining visibility. The bulb’s size and shape are optimized for mogul-base fixtures used in street luminaires and parking structures. Lifespan is listed around 20,000 hours, making it a practical option for sites needing extended service intervals.
Sunlite 03663 MH400/U/MOG 400W MH Lamp
The Sunlite 03663 MH400/U/MOG is a 400-watt metal halide bulb with a mogul E39 base. It delivers up to 36,000 lumens with a color temperature of 4000K, offering high efficacy and bright color rendering suitable for outdoor municipal and commercial lighting. The larger mogul base fits many street and parking lot fixtures, and the 12,000-hour life span supports longer service between replacements. This option is ideal when high lumen output and color fidelity are priorities in outdoor settings.
Sunlite MH250/U/MOG 250W MH Lamp
The Sunlite MH250/U/MOG provides 25,000–21,000 lumens at 4000K with a mogul E39 base. This 250-watt metal halide lamp is well-suited for mid-range outdoor lighting needs, delivering strong luminance for streets and campus walkways. Its clear finish ensures efficient light output, while the 15,000-hour lifespan reduces maintenance frequency in high-traffic outdoor zones. The E39 base and fixture compatibility make it a practical upgrade path for older HID installations.
Mafuken 500W LED Corn Light Bulb
The Mafuken 500W LED Corn Light uses a 60W LED module configured for high output, delivering up to 7,500 lumens with a 5000K daylight color temperature. This LED corn light is designed for direct-wiring, with no ballast required, and provides broad 360° illumination ideal for large outdoor areas, warehouses, and garages. With a long estimated lifespan of over 50,000 hours, it reduces replacement cycles and maintenance costs in industrial outdoor settings. The E26/E27 compatibility adds fixture flexibility for various installations.
Buying Guide: Key Purchase Considerations
When selecting bulbs for outdoor street lighting, several factors determine long-term performance and total cost of ownership. Consider the following perspectives to balance brightness, efficiency, and reliability:
- Bulb technology: HID options (HPS, MH) offer high brightness with strong outdoor performance but require ballasts and can have longer warm-up times. LED options provide instant illumination, higher energy efficiency, and longer lifespans, with varying color tones that affect visibility and comfort at night.
- Base type and fixture compatibility: Ensure the base (E26, E39 mogul) matches your existing fixtures. Larger mogul bases are common in street luminaires, but not all outdoor fixtures support them. Verify ballast compatibility for HID lamps and consider ballast-compatible LED adapters if upgrading.
- Lumen output and distribution: Outdoor lighting benefits from high lumens and wide distribution. Higher wattage HID bulbs deliver more lumens but may have higher running costs. LEDs often yield similar or greater lumens with lower wattage and better efficiency.
- Color temperature and visibility: Warmer tones (around 2100K) can create a welcoming environment but may reduce color differentiation. Cooler daylight tones (around 4000K–5000K) improve visibility and contrast, which can be important for security and wayfinding.
- Lifespan and maintenance: LED bulbs typically offer the longest lifespans and lowest maintenance, while HID bulbs require periodic replacements and ballast checks. Factor replacement schedules into total cost of ownership.
- Energy efficiency and operating costs: LED options generally incur lower energy costs over time, offsetting higher upfront prices. For existing HID fixtures, switching to efficient LED retrofits can be cost-effective if compatible with fixtures and controls.
- Environmental and safety considerations: Outdoor bulbs should be rated for weather resistance and rated for outdoor use. Consider fixture placement for glare control, light trespass, and dark-sky compliance where applicable.
- Installation and accessibility: Direct wiring vs. ballast-dependent setups influence installation time and ongoing maintenance. Ensure electrical codes and fixture ratings are followed for outdoor installations.
Overall, the five products highlighted here cover a spectrum from traditional HID to modern LED for outdoor street lighting. Selecting the right option depends on fixture compatibility, desired brightness, energy goals, and maintenance considerations for your specific outdoor environment.
